The Effects Of Ph On Enhanced Biological Phosphorus Removal (Ebpr) With Propionic Acid As The Dominant Volatile Fatty Acid (Vfa), Seyed Malekjahani Jan 2006

The Effects Of Ph On Enhanced Biological Phosphorus Removal (Ebpr) With Propionic Acid As The Dominant Volatile Fatty Acid (Vfa), Seyed Malekjahani

Electronic Theses and Dissertations

pH control is a tool to improve some aspects of Enhanced Biological Phosphorus Removal (EBPR) process. Filipe et al (2001a, 2001b, and 2001c) found strong evidence that the stability of EBPR systems can be improved by increasing the pH of the anaerobic zone, thereby creating conditions where phosphorus-accumulating organisms (PAOs) are able to take up acetate faster than glycogen-accumulating organisms (GAOs). They explained this observation by comparing the growth rate of phosphorus-accumulating organisms (PAOs) and glycogen-accumulating organisms (GAOs) and found that pH has little effect on PAOs growth rate but adversely affects GAOs growth rate when it increases (at pH …

Density-Functional Theory Applied To Problems In Catalysis And Electrochemistry, Santosh Kumar Jan 2006

Density-Functional Theory Applied To Problems In Catalysis And Electrochemistry, Santosh Kumar

Electronic Theses and Dissertations

We study the structure and energetics of water molecules adsorbed at ceria (111) surfaces below one monolayer coverage using density-functional theory. The results of this study provide a theoretical framework for interpreting recent experimental results on the redox properties of water at ceria (111) surfaces. In particular, we have computed the structure and energetics of various absorption geometries at stoichiometric ceria (111) surface. In contrast to experiment results, we do not find a strong coverage dependence of the adsorption energy. For the case of reduced surface, our results show that it may not be energetically favorable for water to oxidize …
